IDM HD1080P Multi-E1 HD Video Codec Transmission Device

The IDM HD1080P Multi-E1 HD Video Codec Transmission Device provides bidirectional HD video (1920x1080P 60fps) transmission over 2 to 4 E1 links. When 3 or 4 E1 links are used, it can also provide one Ethernet transmission interface simultaneously.
With 2 E1 links, the 1080P 60fps format can be transmitted smoothly; with 3 E1 links, the image is nearly identical to the original. The transmission delay from encoding input to decoding output is less than 100ms. The Ethernet interface on the device can be used as a configuration monitoring interface, a software encoding/decoding interface, or a transmission interface.
This device can also be simplified to unidirectional HD audio/video transmission.
